For American travelers who pass through certain cities, biometric scanning and boarding have already become a well-known way of life. Biometric boarding is becoming more popular, and one of the country’s biggest airlines introduced it at its biggest hub.

Last week, American Airlines brought biometric boarding to Dallas/Fort Worth International Airport. Right now, the technology is only available on certain international flights departing out of terminal D. It allows passengers to board using a seconds-long facial scan instead of the traditional boarding pass. American assures passengers no biometric data will ever be stored.

American offers 91 international flights out of the airport every day. By the end of the year, the airline intends to offer biometric boarding on upwards of 70 daily flights out of terminals A, B, C and D.

“American is committed to ensuring that DFW remains a premier gateway,” said Cedric Rockamore, vice president, DFW hub operations, American Airlines. “As its largest hub, implementing new technology like biometric boarding gives us the opportunity to enhance the airport experience in partnership with CBP. This new technology allows us to provide a more seamless and modern experience for both our customers and team members.”

The process relies upon cooperation with U.S. Customs and Border Patrol. When beginning the boarding process, an image of the passenger’s face is sent to the CBP database in order to match with the stored passport photo on file. If the computer clears the passenger for boarding, they can board right away. If there is a problem, they can board via standard procedures.

According to CBP officers, the process makes airline travel more efficient and secure.

American Airlines previously instituted biometric boarding in Los Angeles (LAX).
